Parking Assistance Device with Dynamic Initial Position Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assisting devices fail to appropriately guide vehicles to a parking initial position from which they can be directed to a target parking position, especially when the starting position of the parking operation is not optimal relative to detected obstacles or parking frames.
Innovation Solution
A parking assisting device equipped with an ambient area detecting unit to identify obstacles or parking frames, a guiding unit that adjusts guidance based on the vehicle's distance to these obstacles or frames, and an information output system to inform the driver in an audiovisual manner, with adjustable start timings for guidance and automatic running features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the parking assisting operation is started from any position, then the operation can be initiated, but the vehicle may not be appropriately guided to the parking space
Solution Approach 1:
The system performs preliminary detection of the parking space and calculation of the appropriate parking initial position before the parking operation is initiated. The guiding unit then guides the vehicle to this pre-calculated position, ensuring that the vehicle is in the correct starting position for successful parking assistance.
Solution Approach 2:
The system continuously monitors the vehicle's position relative to the calculated parking initial position and provides guidance feedback to the driver through the message unit. The guidance is adjusted based on the vehicle's current position, ensuring accurate arrival at the parking initial position.
2Productivity
If the vehicle is guided to a parking initial position that is not optimal, then the parking operation can proceed, but the parking may not be appropriately completed
Solution Approach 1:
The control unit calculates the optimal parking initial position in advance based on the detected parking space parameters and vehicle characteristics. This pre-calculation ensures that the vehicle is guided to the precise starting position needed for successful parking, rather than attempting parking from any arbitrary position.
Solution Approach 2:
The system adjusts the parking initial position parameters based on the detected parking space dimensions, obstacle positions, and vehicle characteristics. By dynamically changing these parameters, the system ensures optimal parking guidance for each specific situation.

AI summary
A parking assisting device includes an ambient area detecting unit that detects an obstacle or a parking frame in an ambient area surrounding a vehicle, and a guiding unit guides the vehicle to a parking initial position from which parking of the vehicle to a parking space, adjacent to the detected obstacle, or the detected parking frame is permissible. In the parking assisting device, a guidance mode in which the guiding unit guides the vehicle to the parking initial position is set up based on a distance between the vehicle and the detected obstacle or the detected parking frame in a vehicle width direction of the vehicle.
